What is metallic support.pkg and do I need it..

Hi OCLP fans,

Great package. Quick one:

I have a MBP mid 2012 and have just installed Sequoia 15.7.4 exactly as per the install guide. With some hiccups but it’s gone through.

This MBP has Intel HD 4000 integrated graphics and also the Nvidia 650GT discrete.

Do I need to install this Metallibsupportpkg, as shown here?

If so, how do I determine the exact build of my MacOS version?

I ran the post install root patch as instructed, OCLP reported it was all already in place.

Thanks!

Additionally, is there a way post install (as I am) to verify that everything is working ‘as expected’
